Specific implementation mode
It is real below in order to make the technical means, the creative features, the aims and the efficiencies achieved by the present invention be easy to understand
1 to 4 pair of the example combination attached drawing mounting assembly provided by the invention for being convenient for bellows with pipe fitting to be connected is applied to be specifically addressed.
Refering to fig. 1 and Fig. 2, for ease of the structural exploded view for the mounting assembly that bellows is connected with pipe fitting；In conjunction with Fig. 3 and figure
4, the stereogram of connecting cylinder in the mounting assembly being connected with pipe fitting for ease of bellows.And it is the structure of clear display the present embodiment
Feature is omitted in figure and shows part-structure.And it defines and is by the direction of adapter to connecting cylinder to bellows as shown in Figure 1
Direction from the front to the back.
As shown in Fig. 1 to 4, the mounting assembly provided by the invention being connected with pipe fitting convenient for bellows include connecting cylinder and
Adapter, wherein connecting cylinder includes outer barrel 1, has the inner cylinder 2 of annular in outer barrel 1, and 2 rear end of inner cylinder is fixed on outer barrel
The madial wall of body 1,2 front end of inner cylinder are uniformly provided with the notch that multiple tracks axially extends and form first annular toothing, inner cylinder 2
Lateral wall and the madial wall of outer barrel 1 between formed annular installation cavity, 5 one end of bellows is planted by connecting cylinder front end into installation
Intracavitary and the madial wall that bellows 5 is abutted by the lateral wall of 2 front end of inner cylinder；
Adapter include the shape for hat connector 3 being connected from the front to the back and tubular tensioning head 4, shape for hat connector 3 it is interior
There is side wall the internal thread (not shown) to connecting pipe, 4 front end of tubular tensioning head to be uniformly provided with multiple tracks in an axial direction
The notch of extension simultaneously forms the second annular toothing, and the front end of tubular tensioning head 4 stretched by the rear end of connecting cylinder and and with it is interior
2 mutual clampings of cylinder；
Also, the second annular toothing is gradually spread out on direction from the front to the back, i.e., diameter from the front to the back gradually increases
Greatly, and after stretching into connecting cylinder it is mutually twisted with first annular toothing, specifically, first annular toothing, the second annular tooth
The notch quantity and width all same opened up in structure, and the riser size formed between width of rebate and adjacent notch is identical.?
The annular toothing of two of interlaced setting can further compress the madial wall of bellows 5 after being overlapped mutually so that close
Envelope property is more preferable.
Based on the above-mentioned technical proposal, 5 connection component of bellows includes connecting cylinder and adapter, and connecting cylinder includes outer barrel 1,
Adapter include shape for hat connector 3 and tubular tensioning head 4, bellows 5 is planted by connecting cylinder front end and by installation cavity inside and outside
Side wall clamps bellows 5, and the rear end that head 4 is tensioned by tubular is spirally connected connecting pipe, enabling is easily connected to bellows 5
In connecting pipe, piping connection is carried out again it is not necessary that its front end is additionally drawn into light-pipe structure after bellows 5 is cut, it conveniently can
It leans on, and leakproofness is preferable.
In a preferred embodiment, it in offering one of annular groove 6 on the madial wall of inner cylinder 2, is tensioned in tubular
There is the annular protrusion 7 to match together with annular groove 6, to be planted into connecting cylinder by tubular tensioning head 4 on first 4 periphery wall
Afterwards, annular protrusion 7 is caught in annular groove 6 and realizes clamping effect.Further, outer barrel 1 and inner cylinder 2 are integrated.Further
, the rear end of connecting cylinder offers the first half slot 9 being circular layout together, in tubular be tensioned head 4 front end face offer with
The second opposite half slot 8 of first half slot, 9 position, and after the 8 mutual split of the first half slot 9 and the second half slot constitute to
The round slot structure for accommodating O-ring, to further realize leakproofness.Further, in offered on the madial wall of outer barrel 1 with
The thread groove (not shown) that the periphery ripple struction of bellows 5 matches, enabling connected connecting cylinder in a manner of screwing
Bellows 5 is connect, and mutual connection is more firm, is not easy to.Further, in also embedding on the madial wall of outer barrel 1
Equipped with a rubber ring (not shown), to further function as sealing effect.Further, on direction from the front to the back, the
One annular toothing is also abducent, i.e., diameter gradually increases, but extended amplitude is less than the second annular tooth structure extension
Amplitude.
In specifically used, bellows 5 is directly planted by screw thread in installation cavity, then is planted into cylinder by connection tube rear end
Shape is tensioned head 4, until annular protrusion 7 is embedded in into 6 mutual clamping of annular groove, can appropriate turn shape for hat connector 3 so that two rings
Mutual clamping between shape toothing, i.e., in the riser card merging notch between adjacent notch, but can not also turn, the first of inner cylinder 2
Madial wall of the annular tooth structural outer rim against bellows 5 so that bellows 5 is pressed in installation cavity, and shape for hat connector 3
Rear end screws connecting pipe, you can realizes the connection of bellows 5.In addition, tubular tensioning head 4 and shape for hat connector 3 are along axis
It offers to by the channel of combustion gas.
In addition, as a kind of different embodiment, substance is same as described above, the difference is that, in this reality
It applies in example, inner cylinder 2 is made of plastic cement or rubber material, and outer barrel 1 is made of metal material, and tubular is tensioned head 4 then can be with
Plastic cement or rubber or metal material, and inner cylinder 2 with outer barrel 1 be not it is integrated, specifically can by being clamped, be spirally connected or
Other modes are realized such as the mode being directly embedded when producing so that itself have elastic, better tightness, and in this implementation
In example, 2 front end of inner cylinder does not open up first annular toothing, and 4 front end of tubular tensioning head does not open up the second annular toothing yet, completely
By the two abut after to 1 direction of outer barrel compress bellows 5, plastic cement material itself have elasticity and sealing characteristic, energy
Enough effects for equally realizing convenient and reliable interconnection and sealing.
The foregoing is merely presently preferred embodiments of the present invention, is merely illustrative for the purpose of the present invention, and not restrictive
's.Those skilled in the art understand that in the spirit and scope defined by the claims in the present invention many changes can be carried out to it,
It changes or even equivalent, but falls in protection scope of the present invention.
